She used 1/3 or the paint on each fence post
108 miles 3 hours = 36 mph upstream
108 miles 2 hours = 54 mph downstream
bv = boat velocity in still water
cv = current velocity
bv -cv = 36
bv +cv = 54 Adding both equations
2*bv = 90
boat velocity in still water = 45 mph
since bv + cv = 54
then we know the current velocity = 9 mph
Answer:
360 m/hr
Step-by-step explanation:
speed = distance/time
So, the slower butterfly can fly
(1866-66)m/5hr = 360 m/hr
